[WIN32] [WINCE] [UNIX]
dp4home=System dependent default
This value specifies the directory where the local DP4 licence file is stored. The same location is also used for the default userdata.sys file, and may be used for other files (for example the DP4 terminal server creates its temporary cache files in subdirectories of this directory.)
You only need to specify a value for this entry if you want to store dp4.sys other than in the default location for the operating system. You are recommended not to do this.
See Names and Locations of Configuration Files for details of how the default value is determined.
